ok, well finally I was fed up and pushed the reset button, sometimes …
problems in order solved
depreciation problem and related → uart pins very sensible on this unit and needed to keep the little adapter very tight.
what sketch works on emontx V3.4 for me : → loaded the emonTxV3_4_DiscreteSampling (src) sketch (not the other one I mentioned earlier)
set datacodes = h,h,h,h,h,h,h,h,h,h,h,L to all emontx nodes to have them all equal and not half/half
seems to work again … finally all the emontx calibrated for voltage
to Robert and Paul, thanks for pushing in the right direction
